How to Make Trees Grow Bigger & Faster
All you need to jump start the growth of your tree is a PVC pipe or a deep root sprinkler. The first thing you need to focus on throughout this process is root feeding. Shooting water from a hose on the top of a tree root is not only a waste of water, but extremely inefficient. This is because the water cannot easily penetrate the soil deep enough to soak through and feed the roots. Instead of this malpractice, you should try to direct the water as straight to the roots as possible. One way to do this is to put a PVC pipe in the ground directly under the foliage, fill the PVC pipe with water, and now the water will go directly to the roots of the tree. Another method for getting the water as direct to the roots as possible is to use a drip line around the tree.
This reduces the water flow, allowing the soil enough time to properly absorb the water while directing it right to the roots. The trick with drip feeding is to leave the drip feeders on for a longer period of time because such a small amount of water is being produced. Thirty minutes or longer is your best bet for most trees. Another option is directing the water straight down to the roots through a root irrigation stake, which attaches directly to your house and is then stuck deep into the soil.
The last step is to select a high potent fertilizer and put it through whatever drip feeding method you choose. By doing this, you ensure that the fertilizer goes straight to the roots. Tree roots should be fertilized every one to two months and it will lead to much larger leaves and a much faster growth rate.
